To all whom it may concern: v

Be it known that I, SAMUEL HUDSON, a

citizen of the United States, and a. resident of Los Angeles, in thecounty of Los Ang eles and State of Califprnia, have invented new anduseful Improvements in Haircomplishing its purpose. Obviously the DryingApparatus, of which the following is a specification.

This invention relates to hair drying apparatus and has for itsprincipal object to provide for increased efliciency of operation whileproviding for greater comfort to the subject.

While my invention is applicable to use under all conditions for dryingthehair, particular consideration is given to providing an apparatuswhich may be used under conditions where the hair to be dried is held inwavers, curlers or the like, as in the art of producing semi-permanentwaves. It is obvious that in the above instance the strands of hair arenot free to be acted upon by the air currents in theusual manner, and itisv therefore important, and it is one of the primary objects of theinvention, to quite positively direct and dis tribute the air currentsemployed.

It will be understood in the consideration of the invention that theusual hair drying apparatus consists 0f a blower cagable of, supplyingwarm air, and a flexible ose for directing the warm air... The usualprocedure is to secure a towel .'or the like around and over thesubjects hair, and to tie this towel to the flexible tube in such amanner that the towel receives all the air and holds itpocketed adjacent'the subjects head until saidair can escape through the intersticesof the towel fabric. The most satisfactory type of blower used is thecentrifugaltype, which displaces a large'vol ume of air but at anecessarily low pressure. Hence the difliculty with which the air. canescape under the conditions of the above'described procedure, sets up aback pressure and appreciably lowers the efiiciency of the apparatus.Also a pocket of. air forms adjacent the subjects hair and scalp, whilethe fresh warm air simply flows over the inert pocketed air and escapeswithout acpocketed air becomes fully saturated and can absorb no moremoisture from the hair. I have also found the flexible hose to-becumbersome to handle, and at times incon- 1 throughout all to thedevice.

venient to the subject. It is usually necessary to maintain a higher airtemperature Y in the above procedure, todiscomfort.

In view of the foregoing it is another object of the invention toprovide a hair drying apparatus capable of setting up a flow of heatedair over the subjects head and hair in a manner to quickly absorb andcarry away the moisture therefrom without subjecting the blower to aback pressure and in a manner to insure even drying efi'ect parts of thehead subject the subjects Another object of the invention is to providea device of the above character capable of readily being adjustedinelevation and in which the porting;

Another object of the invention. is to provide a hair drying apparatusin which due'consideration is given to sanitationby parts 'are rigid andself supproviding for any part of the apparatus coming in actual contactwith the'subject being removable for washing and sterilization. o i

Other objects and advantages of my invention will appear hereinafter andwill be better understood by virtue of their 00- ,currence in thespecification.-

I have illustrated by the accompanying drawings a preferred embodimentof my invention, and it is conceived by me that numerous changes inconstruction and arrangement of parts and other embodiments will suggestthemselves to the minds of those skilled in the art, and I do not limitmyself to any specific construction or arrangement of parts, but mayalter same as I desire, without enlarging the scope of my invention, andwithout departing from the spirit thereof, within the appended claims.

In the said drawings, a .Figure 1, is a view mainly in elevation of myimproved hair drying apparatus;

Figure 2, is a; view in enlarged detail vertical section of a part ofthe apparatus hereinafter termed the hood.

.Figure 3, is a ,view in section seen on a 7 line 3-3 of Fig. 1 lookingthe direction 2 parts, 4 indicates a blower operable by an outwardly,and through this space air section 11 of said air conduit.

discharged from the blower. Blowers of this type for delivering warm orcold air are well known and need not be specifically described orillustrated herein.

[To the spout is affixed an air conduit 8 asby a bayonet lock 9, wherebyit is readily detachable. In keeping with the objects of the inventionsaid conduit is preferably rigid, but for the purpose of increasing ordecreasing its effective length, it is here shown as made up of aplurality of relatively telescoping sections 10, 11, etc.

Now it will be apparent that upon the blower being put in operation andthe heating element energized volumes of warm air will flow through saidconduit.

One of the salient features of my invention resides in an air directinghood 16,

which is formed of a rigid material, such as sheet metal, and imperviousso that air cannot escape therefrom except in the manner hereinafterexplained. Said hood isof substantially inverted bowl shape and isformed with 'an air admission aperture as at 17. Said apertureis'slightly elliptical in form and is partially closed by a shield 18,which forms an integral portion of a Said shield is formed withanaperture 19,'whereby air flowing through said conduit may enter saidhood. The hood is secured pivotally to the conduit section 11 by a pin20, which passes through both the hood and the said section. It will beapparent now that the hood may be moved to various angular positionsrelative to the major axis of the hood, while the shield 18 will serveto keep the joint between the hood and the conduit suitably air tight.

The blowers of the. type shown are generally mounted so as to eoscillatable about their centers for adjustment purposes, and in theembodiment shown, said blower is shown as mounted on an arm 21 directlyat its center, and said blower may be held in any adjusted position bytightening a thumb screw 22 which co-acts with the arm' and blowercasing in the usual manner to promote frictional engagement between theprovision for swinging thehood relative to Leas es the conduit, and bythe provision of a. telescoping air conduit, the hood may be adjusted toany vertical and forward position with respect to a surface'or otherfixed element 23, to which arm 21. is attached.

Air entering the hood and having the usual velocity, or the usualpressure behind it, will be forced downward in, and will spread out andfill, all portions of the hood as indicated b the arrows in Fig. 2, andwill be compel ed to flow to the lower edge 2st thereof before it canescape. Extending around and preferably-below, while being spaced fromthe outer surface of the hood, an annulus 25 is provided. Said annulusalso extends upwardly a suitable distance above the lower edge of thehood. Thus a vertically rising air discharge space 26 is provided whichextends annularly around the lower portion of the hood.- Thus acounter-flow of air is set up. The air rising in space 26 flowingcontrary to the air descending within the hood serves to keep the hoodand annulus at practically the same temperature so that the tendency ofmoisture to precipitate, immediately the air leaves the hood, issubstantially reduced. Another purpose of the annulus is to provide fora flexible skirt 27 being supported thereby so that air cannot flowdownward aroun the subjects face, and said skirt of course serves toretain the hair of the subject within areas swept by the warm aircurrents. Said skirt is preferably of a pliable material and capable ofbeing removed for Washing and sterilizing, although it is conceived thata common towel may be temporarily bound around the subjects head and theannulus jointly in place of saidv skirt.

Tnteriorly of the conduit, at the end where it discharges to the hood, abafile 28 is secured to the conduit; said baflie is "made of a soft.metal so as to be capable of being bent into dotted'line position, andmay be employed to redirect the air currents should j While theoperation and application of the device is practically apparent from theforegoing it may be better understood from the following: The hood ispositioned suitably'over the subjects head, as indicated in Fig. 2, andthe flexible skirt or a towel secured around the annulus as shown toplace the subjects hair i' in substantially direct communication withthe interior of the hood. Air entering the hood will flow in thedirection indicated and will thus be compelled to actually 'contact withthe subjects head and hair. The drying effect of heated and expanded airin constant motion and constantly renewed is well known, and it will vbeapparent noW that I have provided an efiicient hair dryin apparatus byallowing the air to enter an escape freely, and without setting up aback pressure on the blower, while being quite accurately and positivelydirected. Any of the well known means common to warm air distributingapparatus may be employed for controlling the temperature of the air.

While I have shown and described a specific embodiment of my invention,I do not limit myself thereto, but may alter the construction andarrangement of parts as occasion requires, and may otherwise modify theap aratus within the limits of the appended claims.
